Try @ARGV (all caps) - that is what it should be. I don't know why @argv works at all. Pulling an element from an array should use '$': $ARGV[0] -not- @ARGV[0] Also, get in the habit of starting all your scripts with: use strict; use warnings; my $test= $ARGV[0]; # proper format die "nothing in array" unless $test; # unless is easier to read print $test, "\n"; # added newline Aloha => Beau; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
